我有一个我认为很奇怪的问题。
使用与 servlet 的相同映射，一个 url 有效，而另一个无效：
<servlet-mapping>
<servlet-name>UL_Admin</servlet-name>
<url-pattern>/universal_listings_administration/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Create_New_Site</servlet-name>
<url-pattern>/universal_listings_administration/sites/new_site/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Create_New_Site</servlet-name>
<url_pattern>/universal_listings_administration/sites/delete_site/*</url_pattern>
</servlet-mapping>
Create_New_Site 适用于 /universal_listings_administration/sites/new_site/* 但不适用于 /universal_listings_administration/sites/delete_site/*
当转到 /universal_listings_administration/sites/delete_site/* 时，该站点只需转到 UL_Admin ！！！
我改变了网址的顺序，但得到了相同的结果。我在不同的浏览器上试过这个，认为这可能是一个缓存问题，但每次都得到相同的结果。
有人知道这里发生了什么吗？？？
我认为可能是我的过滤器或其他东西？我看过了，但过滤器似乎一切正常。无论如何，这是我在 web.xml 中的安全和过滤器设置
<security-constraint>
<web-resource-collection>
<url-pattern>/universal_listings_administration/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<url-pattern>/jsps/admin/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<url-pattern>/stylesheets/admin/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>

更新：
我做了一些调试，我确定我将访问正确的 URL，（从 web.xml 复制、粘贴），这是我在请求第一个过滤器时得到的内容（比较 create_site 和 delete_site：
create_site: http://www.example.com:8888/universal_listings_administration/sites/new_site/ _pathInfo: "/" _requestURI: "/universal_listings_administration/sites/new_site/" _servletPath: "/universal_listings_administration/sites/new_site" _uri: "/ Universal_listings_administration/sites/new_site/"
delete_site: http://www.example.com:8888/universal_listings_administration/sites/delete_site/ _pathInfo: "/sites/delete_site/" _requestURI: "/universal_listings_administration/sites/delete_site/" _servletPath: "/universal_listings_administration" _uri: "/ Universal_listings_administration/sites/delete_site/"
我想现在我必须弄清楚为什么 _pathInfo 和 _servletPath 完全不同......
